Abstract: The system for and a method of generating a scent and an image based upon a coded signal transmitted from a remote location, and the scent is generated from a dry scent carrying medium which contains a plurality of independent sources of scent causing agents. The coded signal is indicative of simultaneously activating the independent sources of scent causing agents so as to generated a complex mixture of the scents on the fly.

Abstract: A method is disclosed whereby a motion picture projector is equipped to operate at two or more different speeds, such as 24 and 30 frames per second. It is envisioned that different parts of a motion picture may be recorded at different frame rates, to variably impart a highly intense effect upon the audience, expanding the parameters of creative control for the producer of the film. In operation, the method described facilitates switching between these different frame rates, both during the presentation of a single motion picture and between pictures. Cue signals recorded onto the film actuate the change in speed. The projector is automatically set to switch operation into a different speed, and the frames of the film that will be shown during the transitional period are prepared to give the audience the impression of a smooth transition between speeds.

Abstract: A method of conditioning a person's unconscious mind in order to effect a desired change in the person's behavior which does not require the services of a trained therapist. Instead the person to be treated views a program of video pictures appearing on a screen. The program as viewed by the person's unconscious mind acts to condition the person's thought patterns in a manner which alters that person's behavior in a positive way.

Abstract: A zoom lens barrel is constructed such that the axial movement and rotation of a single operation ring relative to a stationary barrel causes zooming and focusing respectively and provides a device for providing constant magnification photography. This is accomplished by a plurality of cam grooves provided on one of the operation ring and the stationary barrel and a guide pin provided on the other of the operation ring and the stationary barrel and releasably engageable with each of the cam grooves. Each of the cam grooves forces the operation ring to rotate upon axial movement of the operation ring through the engagement with the guide pin such that magnification remains constant during focusing. The magnification that remains constant during focusing varies depending on which of the cam grooves the guide pin is engaged with.

Abstract: A process for forming, on a photosensitive support, images presenting a dissolve, this process comprising the steps which consist in forming first and second primary light images by projection on a screen of respective light beams, the light images overlapping and presenting a dissolve, in cutting off the second light beam, in taking a front photograph of the first light image on the photosensitive support by means of an apparatus, in retablishing the second light beam and cutting off the first light beam, in moving the photosensitive support within said apparatus and in taking a front photograph of the second light image.

Abstract: The frame-counting device is primarily intended for use with a film cassette in titling and lap dissolve operations. The film cassette contains an unexposed film having a series of perforations and is of the type having a side wall formed with an opening which defines a film plane and through which the film is exposed. The device includes the following structure: a housing having an aperture for receiving the film cassette with its open side wall ahead, a transport sprocket which is rotatably mounted in the housing and engageable with the perforations of the unexposed film of the cassette received in the aperture of the housing, and a member for shielding the film plane of the cassette as received in the aperture against an access of light. A counter is carried by the housing, which counter is readable from the outside and operatively connected inside the housing to the transport sprocket.

Abstract: The operator projects motion-picture film using a projector. A counter counts frame pulses during both forwards and reverse film transport, and thereby keeps track at all times of the film frame count. The operator during forwards projection when he sees the start or end of a scene pressss a storage switch which causes the scene-start or scene-end frame count to be stored. The operator also preselects the type of recording-transition effect to be implemented. The operator then commands dubbing of the scene, whereupon a minicomputer begins to automatically implement a series of operations, including projector motor control and recording control, to implement the selected recording-transition effect, in a programmed manner dependent upon the stored frame counts and the instantaneous frame count. In the middle of the dubbing of a scene, the operator can change the transition effect he selects, to produce a transition effect at the scene end different from that selected for the scene start.

Abstract: In a motion picture camera in which films of different length can be loaded, a film end indicating device is provided to indicate that the film has come to its end regardless of its length. The film end indicating device is comprised of an indicator and a plurality of end detectors attached to a footage counter in the camera to detect the end of the film of different length respectively. A change-over lever is provided between the indicator and the plurality of end detectors to selectively connect one of the detectors to the indicator according to the length of the film.

Abstract: A programmable exposure control device for use on a photographic film printer for producing special effects in motion pictures such as a fade-in, fade-out, lap dissolve or other numerous special effects requiring variations in printing beam intensity. The exposure control device comprises a mechanical shutter capable of progressively varying the intensity of the printing beam at any predetermined rate. A control system is provided for operating the shutter and includes a memory portion for storing preselected operating curves for a plurality of film exposure characteristics. The control unit is connected to a tape reader for supplying information to the control unit, for example, relating to the length of the particular fade desired. The tape reader also may provide information for controlling the position at which a fade or other special effect is to begin or end.

Abstract: A pair of signals optically different in consistency is placed on an image information recording film to be projected. A projector is provided with at least a pair of light detection elements in a position where signals may be detected. The difference between outputs from the elements is utilized as a detection signal. The above-described signals are detected by way of an ordinary speed of the film so as to automatically switch the projection mode thereof to other projection modes, such as a still projection mode, a slow motion projection mode, a fading projection mode, and still projection mode for the search and after the search. For this purpose there are provided with a control circuit for processing the output of the detection element and a drive mechanism for providing the respective projection mode in response to the output signal from the control circuit.
